The weather gradually began to warm up, many car owners are planning to travel in the spring, but with the arrival of spring, the temperature difference, humidity changes are larger, if not timely maintenance will leave hidden dangers for the healthy use of the car, today for everyone to sort out the spring maintenance precautions.
* Clean the heat dissipation system
The first thing to talk about is the circulatory system, which includes two parts: oil road and water road. After a winter of sand and wind test, the radiator of the car water tank and the condenser of the car air conditioner must have attached a lot of dust, these small dust caused the water tank heat dissipation unfavorable, the engine water temperature is too high, the summer air conditioning is not cool and other failures, serious will also cause early damage to the car parts, so in the spring must clean the vehicle's heat dissipation system.
* Keep the oil circuit clear
As for the maintenance of the oil circuit in the spring, you should go to a professional repair station to check whether the throttle and fuel injectors and other parts are clean, because the upcoming summer is the peak period for opening air conditioning, and the failure of the above parts will undoubtedly increase the fuel consumption of the car.
* Do a physical examination of the air conditioner
The temperature in spring is not stable, and it is common to rise by 10 ° C, in which case the inspection of air conditioning and refrigeration is more important. Generally, after nearly half a year of deactivation of air conditioners, the refrigerant is likely to leak, so after cleaning the condenser and water tank in the repair shop, the worker should be reminded to check the refrigerant margin. In the spring, some car owners are allergic to pollen and should clean and replace the pollen filter in the air conditioner air inlet at the same time.
* Change the oil
Although most of the cars have now used the oil of the four seasons, in some cities, the oil used in vehicles is still divided into winter and summer, so here is a reminder that it is time to change the summer oil.
* Disinfection inside the car
In winter, many car owners rarely open the window to ventilate, a large number of bacteria have accumulated in the car, and as the temperature gradually rises in the spring, all kinds of bacteria will flourish wildly in the wet car. Therefore, it is necessary to thoroughly disinfect the interior of the car this season. Keep the cab dry and hygienic, especially for car seat cushions, foot pads, air outlets and other parts. At the same time, some of the health dead ends in the car should also be cleaned, and the environment in the car should be kept dry and clean as much as possible. Remind the owner to use a neutral detergent for cleaning when cleaning the interior of the car, and do not use substances containing strong acid and alkalinity. In addition, when cleaning, we should pay attention to avoid corrosion of electrical equipment such as audio, radio, and CD.
* Wiper check
Spring is rainy and wipers are used more frequently. It is recommended to check and clean the wiper in time to avoid the aging and deformation of the rubber strip, which will cause the scratch to be unclean, the vision is blurred, and bring safety hazards.
* Protect the paint surface
At the same time, the acidic components in the rainwater can easily cause corrosion of the car paint surface, which will cause damage to the paint surface of the car over time, so in the spring when there is more rain, special attention should be paid to protecting the car paint surface. The simplest is waxing, and the longer and more effective is to carry out glaze beauty. Either way, it prevents the paint from fading and aging.
* Chassis should be rust-proof
Spring car chassis also need a layer of maintenance. Because after the muddy road after the snow in winter, the car chassis will be covered with thick mud, and the soil contains alkaline agents when the snow melts, which is extremely corrosive to the chassis of the car, and will also block the ventilation holes on the chassis. Go to the place where there is a computer car wash and rinse the dirt off the chassis. If there is a condition, you can do a chassis anti-rust treatment to resist the corrosion caused by acid and alkali to ensure that the chassis will not rust. At the same time, it is also necessary to check the bolts, and the inspection process must be careful, because small omissions may cause unnecessary trouble.
* Replenish coolant
In the spring, the temperature gradually rises, and some friends find that the coolant in the water tank is insufficient, so they use clean water to supplement it. At this time, car antifreeze is not the theme, but the water is easy to generate water alkali, water rust, and the boiling point is low, which is very easy to cause "opening the pot". Therefore, it is not possible to replace the coolant with water at will.
* Engine compartment
The engine compartment is the most important part of the car, like the "bedroom", regular cleaning of the engine compartment can ensure the "health" of the engine. The main cleaning items are dust and oil stains: for dust, it is recommended to clean it with a high-pressure air gun; For oil stains, it can be simply cleaned with a flannel and brush.
* Check tire and tire pressure
In winter, because of the cold weather, the tire rubber is stiff and wear will be larger. So in the spring, be sure to carefully check the wear of the tires, and adjust the adhesion of the four tires to the ground to keep it consistent. Due to the influence of thermal expansion and contraction, the tire pressure will be reduced in winter, and the tire pressure will become higher in the spring when the temperature rises. If the tire pressure is not adjusted in time, it will not only increase the fuel consumption of the car, but also accelerate tire wear. After entering the spring, it is recommended to adjust the tire pressure to the standard value.
* Detect brake oil
Brake oil has a strong water absorption, more rain in the spring, greater humidity, once there is water infiltration, the brake oil moisture content increases the boiling point decreases, and the brake oil performance also decays. There are often soft brakes and longer braking distances, which affect driving safety.
